Did you know ?

Oracle was started in 1977–

it was the name of a project thatLarry Ellison completed even after it was scrapped!

The recording density for data—

aka capacity—

has increased60,000,000-fold in 50 years!

The amount of worldwide information is projected to be 988exabytes

by end of 2010! An Exabyte is a million terabytes

The magnetic HDD is 50 years old. In 1956 IBM introduced 305RAMAC which was the size of a refrigerator, and stored a totalof 4.4 megabytes on 50 doubled-sided, two-foot-diameterdisks. The disk had a purchase price of $10,000,000 perGbyte
